is there a solution to this? is there a serialization wrapper that says "don't track this type just because of this pointer"?
so you want "don't track this particular save - but leave others as normal" Try something like
class A ....
class UntrackedA : public A { ... };
BOOST_SERIALIZATION_TRACK(UntrackedA, track_never);
interesting idea. does this eventually track the object if the base class of UntrackedA is track_selectively and saved through a pointer anywhere else?
for example, an object graph that stores a pointer to its own root (through intermediaries in practice):
class A{ //tracking level: selectively void serialize(...){ ar & a; } A *a; //==this };
class UntrackedA : A{ //tracking level: never void serialize(...){ ar & base_object<A>(*this); } }
void save(UntrackedA *a){ ar << a; }
is "a" serialized twice, or tracked because of track_selectively and the pointer serialization in A::serialize?
lol - I didn't think about this when I responded though I'm sure I did it when I made the code. I'm going to speculate since it's easier than doing any work. class UntrackedA : public A { // instead of this: void serialize(Archive & ar, unsigned int file_version){ boost::serialization:base_object<A>(*this); } // consider this void serialize(Archive & ar, unsigned int file_version){ ar & m_a; // where m_a is a member of a ar & m_b; // other member of a etc ... } ... }; Robert Ramey
